Andy Chow is a lecturer in Civil, Environmental, and Geomatic Engineering. Andy's research lies in developing tools for analysing and managing complex systems. Andy recieved his undergraduate degrees in Civil Engineering and Mathematics from Hong Kong University of Science and Technology; and later his doctoral degree from University College London in 2007. His doctoral dissertation on dynamic optimisation of urban transport systems reveived a Gordon Newell Memorial Dissertation Prize in 2008. Before returning to London in Spring 2010, Andy spent three years as a research engineer at University of California at Berkeley in the United States. His research interests on Healthy Infrastructure include statistical analysis and physical modelling of infectious disease dispersion and outbreaks.

Dr Campos is a civil engineer specialising in environmental engineering with 10 years of practical experience working for a state water & wastewater company in Brazil. In addition, Dr Campos has over 15 years of experience working as lecturer and researcher at various universities, including UK.  Her research interests are broad, varying from modelling the biological and physical processes of slow sand filtration to sustainable and resilient sanitation services. She has experience in a wide variety of projects related to various aspects of water and sanitation, including the reduction of risks in sanitation infrastructure, adapting sanitation to climate change and rainwater harvesting for human consumption. Most of her research work is laboratory or field based, focusing on removal efficiency of pathogens and organic matter by treatment technologies. Dr Campos is a lecturer in Environmental Engineering at the Department of Civil, Environmental and Geomatic Engineering of University College London where she is also the Director of the Environmental Engineering Undergraduate Programme and is currently managing the Laboratory of the Healthy Infrastructure Research Centre (HIRC) at UCL.

Dr Nasar is research associate at HIRG, working on airborne disease transmission in built environments. He has recently completed his PhD in Environmental Sciences at University of Essex,UK. His PhD research work was focused on investigations of air quality in residential  and transport microenvironments in the United Kingdom and  Pakistan. The pollutants studied were airborne bacteria and fungi, particulate matter (mass and number concentration, chemical composition), nitrogen dioxide and carbon monoxide. His research interest includes, transmission of airborne pathogens in different built environments, health impacts of indoor air pollution due to biomass fuels in the developing world, characteristics of nanoparticles from various indoor/outdoor sources, Physico-chemical and biological  properties of aerosols, relationship between indoor/outdoor air quality, Environment – society interaction and ethno-environmental knowledge.

Dr. Lai’s work focuses on biological systems in engineering. She is theleader of the KM Group and director of the Healthy Infrastructure Research Group. The current research themes are 1. Urban chemical and wastewater treatment and 2. Pathogens in the environment - Healthy Infrastructure, Hospital Infection and Indoor Moulds. She got a biology degree from the Hong Kong Baptist University (HKBU), where her final year project was about an application of biosolids from sewage treatment plants. She also has researched on biodegradation of PAH in soil, on the biosorption and biodegradation of dyes in textile wastewater at the Chinese University of Hong Kong where she earned her M.Phil. degree. She received her Ph.D. from Imperial College London studying the environmental behaviour of natural and synthetic estrogens, the most potent group of endocrine disrupting substances. An environmental risk assessment was undertaken to review the hazards, dose-response relationship and exposure pathways of these chemicals. This work revealed the information gaps of the existing knowledge and shaped my study into four environmental processes in the aquatic system, 1. partitioning, 2. bioaccumulation, 3. biotransformation and 3. bioavailability. After her Ph.D., she extended her research interests to aerobiology and environmental controls of airborne infectious diseases at the Harvard School of Public Health. Her projects were Groupd on the application of UV germicidal irradiation in inactivating airborne bacteria and viruses. She also had the honour to learn from different environmental health experts in the areas of mould identification and contamination, ventilation systems and endotoxins study.
